GAS-MAKING APPARATUS- SPECIFICATION forming part of Letters Patent No. 763,455, dated June 28, 1904.

Application filed October 8,1903.

To all whom it 711,051 concern:

Be it known that '1, CHARLES M. BAKER, a citizen of the United States, residing in the city and county of San Francisco. State of California, have invented certain new and useful Improvements in Gas-M aking Apparatus; and

- I do hereby declare the following to be a full,

clear, and exact description of the same.

The present invention relates to an improved apparatus designed more particularly for the manufacture of water and oil gas, although capable for use in connection with the manufacture of either oil or water gas separately,

the object of the inventionbeing to simplify the construction of the apparatus ordinarily employed for such purpose and to produce a machine capable of combining water and oil gases during the production thereof, while at the same time permitting of either class of gas being manufactured within the apparatus, thereby accomplishing in a single apparatus the results generally produced by distinct machines, the invention also residing in certain details of construction for consuming the and the pipe connections therewith for the feeding of oil and steam into the generator. Fig. 2 is a top plan view of the mechanism disclosed in Fig. 1 of the drawings, the generator being partly sectioned; and Fig. 3 is a cross-sectional top plan view of the generator,

taken on line a 00, Fig. 1 of the drawings.

The numeral 1 is used to indicate the generator of the apparatus, and 2 the superheater thereof, connection between the interior thereof being made by the flue or passage-way 3. The interior of the generator is divided into gas-generating chambers L 5 by means of the spaced arches 6 of refractory material. These Serial No. 176,182. (No model.)

arches support or uphold within the chamber 4: the checker-Work 7, constructed of bricks of refractory material so laid or built within the chamber as to leave interstices 8 for the free circulation of heat therethrough.

Withinv the lower chamber 5 of the generator is placed a bed or body 9 of carbonaceous material, which is upheld by the grate-bars 10. Below the ash-pit 11 there is constructed within the wall of the generator, preferably, an annular air-chamber 12, which communicates with the ash-pit 11 through the medium of a series of connecting-fines 13, through which the air is discharged into the said ashpit immediately beneath the grate-bars 10. By means of an opening 14;, closed by the plug, cap, or door 1e, formed in the wall of the generator, access may be had to the interior of the ash-pit for cleaning purposes. A similar opening 15 through the wallof the generator admits of coal, coke, or other carbonaceous material being admitted to the chamber 5 either to replace the consumed material or fororiginal charging. This opening 15 is closed by means of the removable plug, cap, or door 15. It will be understood that the bed or body 9 only partially fills the chamber 5, the upper portion thereof being left free to serve as a gas-space. There is athird entrance-opening 16 formed in the wall of the generator 1, through which access may be had to the upper chamber 4 for insertion or repair of the checker-work 7 This opening is closed by the plug, cap, or door 16. The outlet-flue 17 is closed by the stack-valve 17, which flue leads to the stack 18, suspended above the generator.

Through the wall of the generator, near the bottom thereof, extends the air-blast pipe 17 .which communicates with the air-chamber 12. The air-supply is controlled by the regulating-valve 18 within the pipe 17 With this air-blast pipe connects the oil-supply pipe means of the air-blast supply delivered to the generator and superheater the apparatus may be more quickly heated for the manufacture of gas than by the system at present employed and the interior of the superheater and generator more quickly cleaned after a run by burning out of the lampblack than by removing the same through the stacks.

Having thus described the invention, what is claimed as new, and desired to be protected by Letters Patent, is

1. An apparatus for the manufacture of either water, oil or water and oil gas, the same comprising a superheater, a generator, an upper and lower gas-chamber formed within the generator, the upper chamber being adjacent the superheater and having a conduit forming communication between said upper chamber and the superheater, an oil and steam supply pipe, branch pipes between said supply-pipes and the generator for admitting steam and oil into each of the gas-chambers and beneath the lower chamber, means for closing any of such branch pipes without interrupting passage through the others, and means for supplying a blast of air into the generator at a point beneath the lower gaschamber, said means including a heat-jacketed air-inlet in the surrounding wall of the lower chamber.

2. A gas-generator having its interior divided into two distinct gas-chambers, communication between said chambers, means for supplying steam and oil to each chamber, controlled openings in the wall of the generator for permitting access to be had to each chamber, an ash-pit beneath the lower chamber, and means for supplying an air-blast to the generator from beneath the said lower gaschamber,including an annular inclosed airchamber within the lower chamber, having upwardly-extended open-ended conduits arranged to discharge the air into said ash-pit.

3. In a gasgenerator the combination of communicating superposedgas-chambers, an ash-pit for the lower chamber, oil and steam supply pipes, connecting branch pipes affording communication between said supply-pipes and both gas-chambers, and also the ash-pit of the lower chamber, and means whereby any of said branch pipes may be closed at will without interfering with the passage through the others.

4:. A gas-generator comprising communicating superposed gas-chambers, an ash-pit in the lower chamber, an air-blast communicating with the ash-pit of the lower chamber, oil and steam supply pipes communicating with said air-blast, means for closing said communication, branch pipes communicating with said supply-pipes and both gas-chambers, and means whereby any individual branch pipe may be closed at will without interfering with the passage through the others.

In witness whereof I have hereunto set my hand.
